Meiosis guarantees that in a sexual life cycle, offspring will inherit one complete set of chromosomes (and their associated genes and traits) from each parent. The transmission of traits from parents to offspring is called heredity.
Another important aspect of meiosis and the sexual life cycle is the role these processes play in contributing to genetic variation. Although offspring often resemble their parents, they are genetically different from both of their parents and from one another. The degree of variation may be tremendous.

The following processes are associated with meiosis and the sexual life cycle:
•DNA replication before meiosis
•crossing over
•chromosome alignment in metaphase I and separation in anaphase I
•chromosome alignment in metaphase II and separation in anaphase II
•fertilization



Sort each process into the appropriate bin according to whether it contributes to heredity only, genetic variation only, or both.

C'mon, your question doesn't even include a diagram!

Anyway, from what you've offered, I could be wrong, depending on the viewpoint of your teacher. Realize that if it contributes to heredity, it's something that the next offspring will have, regardless as to weather it's by mitosis or meiosis. I'll sort them into the 3 categories. If you wish for me to explain, post back.

Heredity Only - 1, 3, 5 (if it's asexual)
Genetic Variation only - 2, 4, 5 (sexual), 3 (since crossing over occurred)
Both - All of them

I could easily be wrong, so you may want to check your bio book. Number 3 for Heredity is arguable depending on how you see it. Sorry if I wasn't much help. Hope this helps.

Ok I'm just a tad bit confused on this since there isn't a diagram on the question. Could you please help out with the diagram??

the answer depends from one question to another. If you have the variable DNA replication (assume no error) then the answer is stated as on top. However, if it only mentions DNA replication, I think everything goes in the both category
